Abstract

An external programming system and method for implantable medical devices (IMDs) is disclosed. The external programming system includes a communication circuit, a display device, an input device, and a processor. The communication circuit is configured to link to an IMD to transmit or monitor IMD timing parameter settings. The display device is configured to display a textual representation of an IMD timing parameter setting and a specified IMD timing parameter limit, a graphical slide control comprising a movable feature indicating the IMD timing parameter setting, a graphical slide-control limit corresponding to the specified IMD timing parameter limit, and a graphical representation of physiologic information including a portion of said graphical representation aligned with the slide control movable feature. The input device is configured to adjust the movable feature in response to user input. The processor is configured to monitor or store an IMD timing parameter setting.

3. The system of claim 2 wherein the timing parameter setting for the implantable medical device comprises a configurable cardiac timing parameter selected from at least one of:

Atrioventricular Delay (AVD), Left Ventricular Offset (LVO), Post-Ventricular Atrial Refractory Period (PVARP), Right Ventricular Refractory Period (RVRP), or Left Ventricular Refractory Period (LVRP).

4. The system of claim 3 wherein a graphical slide control feature is configured with a color corresponding to a displayed representation of a portion of a physiologic structure.

5. The system of claim 1 wherein the processor is configured to compare a first timing parameter setting for the implantable medical device against a second timing parameter setting for the implantable medical device, and wherein the processor is configured to detect when the first timing parameter setting is outside a range computed using the second timing parameter setting.

6. The system of claim 5 wherein the display device is configured to change a color of the textual representation of the timing parameter setting in response to the processor detecting when the first timing parameter setting is outside a range computed using the second timing parameter setting.

7. The system of claim 5 wherein the processor is configured to deliver a warning to a user in response to the processor detecting when the first timing parameter setting is outside a range computed using the second timing parameter setting.

8.
